这是应该出现的弹出模式

                                <!-- Form submitted Thank You Modal -->
                                    <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
                                    <div class="modal-dialog" role="document">
                                    <div class="modal-content">
                                    <div class="modal-header">
                                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                                        <h4 class="modal-title text-center" id="myModalLabel">Contact</h4>
                                    </div>
                                    <div class="modal-body">
                                        <h3 class="h3 text-center">Thank you for your feedback! We will get back to you.</h3>
                                    </div>
                                    <div class="modal-footer">
                                        <button type="button" class="btn btn-success" data-dismiss="modal">Close</button>
                                    </div>
                                    </div>
                                    </div>
                                    </div>

JavaScript 文件

    $(document).ready(function() {
      $('#form').validator().on('submit', function(e) {
        if (e.isDefaultPrevented()) {
          // handle the invalid form...
          $('#myModal').modal('hide');
        } else {
          // everything looks good!
          $('#myModal').modal('show');
        }
      })

    });

Answer 1

由于您仅在未调用 preventDefault() 时才尝试显示模式，因此将执行表单的默认操作，即提交表单。这会导致页面加载，并且由于您没有在表单上指定 action 属性，它将提交到同一页面。换句话说，页面只是重新加载。

如果您不想导致页面重新加载，您必须始终调用 preventDefault()，然后使用 AJAX 提交数据。
